But if we go by who predicted TRUMP's "imminent demise" and who didn't, then the only pundits left will be Paul Krugman, Michael Tomasky and kos.
I don't think that's true at all. The "party decides" fundamentalists like Jonathan Bernstein haven't predicted Trump's imminent demise. They've just not aimed to predict the short term polling trends at all, because they consider them irrelevant. Their perspective is that the party elite will get a candidate they like in the end, and who cares who's leading in the polls right now, or tomorrow? (I think Silver has basically been in this category as well. Did he ever predict that Trump would have an "imminent demise" in the polls? I don't think he has, but if someone has a quote from him to that effect, please post it. I think, like Bernstein, he doesn't get too worked up about who's going to be leading in such-and-such a state next week.)
Now, maybe the "party decides" people are going to be proven wrong in an epic way. But let's not get ahead of ourselves, and declare them wrong yet. No one's voted yet. The GOP doesn't yet have a nominee. Let's just wait and see whether they're right or wrong.
I'm talking more about the people who stubbornly refused, despite all evidence to the contrary, to take TRUMP seriously as a candidate and confidently predicted his collapse after he disparaged McCain's service, after he insulted Megyn Kelly, after he feuded with FOX News, after the Paris attacks, etc.
To say even now that TRUMP won't be the nominee is a not unreasonable assumption. But to say that he has no chance, there is some serious delusion and stubbornness there.
